"It's in a Thompson anthology called FIREWORKS and in THE
BLACK LIZARD ANTHOLOGY OF CRIME FICTION. They're both
otherwise pretty hit and miss, so don't pay an arm and a leg
for them."

Well, the Black Lizard Anthology does have at least two other
stories well worth reading: "The Pit" by Joe Lansdale and,
most especially, "The Second Coming" by Joe Gores. The latter
is a tale of two hipsters who sign up to witness an execution
for kicks; the experience has a life-changing impact on both
of them. Highly recommended.
